Thanks Keith and Gilles13. I actually stumbled upon that solution too, but couldn't for the life of me work out what to put between the brackets so the settings apply to all the cars. Each car has an entry like [#05 J] or [#08 M]. In the end I edited each car's veh file and added FIA_F3 to the description. This makes [FIA_F] appear in the realfeelplugin.ini.

No problem. Feel free to update the post you made and include the mod rfm. (note you can't just throw the rfm in as the rfm is tied to the game data files in that media fire link need to replace all the files)! Hopefully perhaps someone knows how to do shadders so it can be brought up to gsce standard.
